Excited state proton transfer dye lasers

Reactions of proton phototransfer in organic compounds and photochemical lasers based on these reactions are considered. A principle of operation of a photochemical laser is described. Selection criteria of acid-base systems to serve as active media in photochemical lasers are determined. A list of acid-base laser systems, conditions of their fabrication, and emission characteristics are collated. Specific losses in photochemical lasers are analysed. Methods of expanding the spectral range of tunable emission in the photochemical lasers are described. The bibliography includes 134 references.
